QX3 Digital Image Gallery
Darkfield Illumination

Tallahassee Pond Scum, Part 1

We have recovered a number of miniature creatures from stagnant fresh water ponds in the Tallahassee, Florida area. Several of these creatures were digitally imaged with the QX3 microscope using darkfield illumination and are illustrated below.

Mosquito Larvae at 10x Magnification

Nematode worm at 60x Magnification

Planaria at 60x Magnification

Darkfield illumination digital images were captured using an Intel Play QX3 computer microscope modified for reflected light darkfield illumination. Oblique light was applied to the specimens using light pipes from a Dolan-Jenner Model 180 fiber optics illuminator containing a 150 watt projection lamp. The mixing chamber and diffusion screen were removed from the stage and a large piece of dark construction paper placed beneath the stage to avoid images of the paper being superimposed over the photomicrographs.
